LSystems and OpenGL

Coursework. Mentor: Polevoy D. V.

Rules definitions (according to Paul Bourke):

Character	Meaning
F	Move forward by line length drawing a line
f	Move forward by line length without drawing a line
+	Turn left by turning angle
-	Turn right by turning angle
[	Push current drawing state onto stack
]	Pop current drawing state from the stack

Building

Dependencies:
1. GLFW
2. GLAD
3. GLM
4. Boost
5. Stb

cmake -S . build -DCMAKE_TOOLCHAIN_FILE=<path_to_pacman>
cmake --build build --config Release
sudo cmake --install ./build
cd build/

Using

./l_system_drawer -h

Available command line keys:

Key	Meaning: format
-gen	Set a number of generations: integer
-len	Set a line length: double
-rot	Set a rotation angle: double
-axm	Set an axiom: string
-rule	Set a new rule: string->string
-file	Set LSystem from the file: filepath
-save	Set file to save screens: filepath

Available keyboard keys:

Key	Meaning
W	Camera up
S	Camera down
A	Camera left
D	Camera right
Q	Camera zoom
E	Camera move away
Z	Take a screenshot

A composition of configuration .txt file (connected by command -file <absolute_path>):

<number of generations>
<length of line>
<rotation angle (degrees)>
<axiom>
<rule 1>
<rule 2>
...
<rule N>

Example 1. Command as follows...

./l_system_drawer -gen 7 -rot 22.5 -axm "F" -rule "F->FF-[XY]+[XY]" -rule "X->+FY" -rule "Y->-FX"

... will produce window with this plant:

Example 2. Another one:

./l_system_drawer -gen 10 -rot 120 -axm "F+F+F" -rule "F->F-F+F"

Example 3. You can specify the absolute path to the configuration file:

./l_system_drawer -file "<absolute path to file>"

Documentation

Technical documentation is here, generated by Doxygen.
You can create documentation yourself, here is a list of possible commands (from install directory bin):

doxywizard Doxyfile
cd l_systems_docs/latex
pdflatex refman.tex

After these actions, you will have a file refman.pdf in this directory.
